The CellTox™ Green Cytotoxicity Assay measures changes in membrane integrity that occur as a result of cell death. The assay is intended to assess cytotoxicity in cell culture after experimental manipulation. The assay system uses a proprietry asymmetric cyanine dye that is excluded from viable cells but preferentially stains the DNA from dead cells. When the dye binds DNA released from cells, its fluorescence properties are s…

The QuantiFluor® dsDNA System contains a fluorescent DNA-binding dye that enables sensitive quantitation of small amounts of double-stranded DNA (dsDNA) in solution.   The quantitation of dsDNA is a very important step in many biological applications, particularly in standard molecular biology techniques. The dye shows minimal binding to single stranded DNA (ssDNA) and RNA, allowing specific quantitation of dsDNA. The…

Recombinant RNasin® Ribonuclease Inhibitor reliably protects your RNA samples from RNase degradation.   RNases are ubiquitous and degradation can cause significant damage to RNA, hindering downstream reactions. Protect your sample with the most robust inhibitor available-- Recombinant RNasin® Ribonuclease Inhibitor. Recombinant RNasin Ribonuclease Inhibitor Features & Benefits:   Inhibits a broad spectrum o…

The CellTiter-Glo® 3D Cell Viability Assay is a homogeneous method to determine the number of viable cells in 3D cell culture based on quantitation of the ATP present, which is a marker for the presence of metabolically active cells.   This ready-to-use reagent is based on the original CellTiter-Glo® Luminescent Cell Viability Assay chemistry and eliminates the need to combine buffer with lyophilized substrate when prepa…

FuGENE® HD Transfection Reagent is a novel, nonliposomal formulation designed to transfect DNA into a wide variety of cell lines with high efficiency and low toxicity. The protocol does not require removal of serum or culture medium and does not require washing or changing of medium after introducing the reagent/DNA complex. Additionally, the FuGENE® HD Transfection Reagent has been shown to support transfection in che…

The NanoBRET™ Target Engagement (TE) Intracellular BET BRD Assay measures compound binding at select BET bromodomain target proteins within intact cells. This target engagement assay is based on the NanoBRET™ System, an energy transfer technique designed to measure molecular proximity in living cells

Hydrolyzes peptide bonds on the N-terminal side of aspartic and cysteic acid residues (Asp and Cys)

All-In-One Processing for Large-Volume Purification Chemistries

Automated Extraction of DNA from Blood or Buffy Coat Samples

Single-Use Ligands for High-Resolution lmaging in Live Cells

The RealTime-Glo™ MT Cell Viabiilty Assay measures viability of cells in a non-lytic, real-time live-cell format, saving time, cells and reagent costs.

Measure neonatal Fc receptor binding  

The Dual-Luciferase® Reporter (DLR™) Assay System(a–f) provides an efficient means of performing two reporter assays. In the DLR™ Assay, the activities of firefly (Photinus pyralis) and Renilla (Renilla reniformis or sea pansy) luciferases are measured sequentially from a single sample. The firefly luciferase reporter is measured first by adding Luciferase Assay Reagent II (LAR II) to generate a luminescent signal lasting at l…

High-throughput quantitation of firefly (Photinus pyralis) luciferase expression in mammalian cells is commonly performed by batch processing of 96- and 384-well plates. Steady-Glo® Luciferase Assay System(a,b,c) is designed for this purpose by providing long-lived luminescence when added to cultured cells. The homogeneous assay provides signal half-lives of over 5 hours in commonly used cell culture media without prior sample…

The CellTiter-Blue® Cell Viability Assay provides a homogeneous, fluorescent method for monitoring cell viability. The assay is based on the ability of living cells to convert a redox dye (resazurin) into a fluorescent end product (resorufin). Nonviable cells rapidly lose metabolic capacity and thus do not generate a fluorescent signal. The homogeneous assay procedure involves adding the single reagent directly to cells cultur…

The Dual-Glo® Luciferase Assay System is a homogeneous reagent system that enables fast and simple quantitation of a stable luminescent signal from two reporter genes in a single sample. This convenient "add-and-read" system generates both firefly and Renilla luciferase luminescence signals from cells that have not been preconditioned or prelysed. With the Dual-Glo® System, internal controls can be established to minimize s…

Use with ADP-Glo™ Assay for bioluminescent detection of kinase activity

The Promega CytoTox 96® Non-Radioactive Cytotoxicity Assay is a colorimetric alternative to radioactive cytotoxicity assays. The CytoTox 96® Assay quantitatively measures lactate dehydrogenase (LDH), a stable cytosolic enzyme that is released upon cell lysis, in much the same way as [51Cr] is released in radioactive assays. Released LDH in culture supernatants is measured with a 30-minute coupled enzymatic assay that result…

The GoScript™ Reverse Transcription System includes a reverse transcriptase and a specialized set of reagents for efficient synthesis of first-strand cDNA optimized for quantitative PCR amplification. GoScript™ Reverse Transcriptase uses M-MLV Reverse Transcriptase and state-of-the-art buffer technology to deliver robust, reliable cDNA synthesis of a full range of rare and abundant transcripts, even in the presence of inhibit…

NanoLuc® and NanoBiT® Luciferase Substrate for Animal Imaging Studies​

It can be challenging to purify sufficient high-quality protein from mammalian cells. Boost protein recovery 30-60% with an optimized covalent protein tag, called HaloTag®. This complete kit offers strong improvements in recovery, purity, cost and protein functionality over historical FLAG® and poly-His tag purification strategies.

The ONE-Glo™ + Tox Assay combines luciferase assay chemistry with a cell viability marker to better understand reporter gene expression in the context of cell health. The assay uses a two-step, addition-only process to make these measurements in a single well of a plate, negating the need to run parallel assays. The first part of the assay is a nonlytic fluorescence assay (CellTiter-Fluor™ Cell Viability Assay) that measure…

The GoTaq® Probe qPCR Master Mix is optimized for quantitative PCR assays in the hydrolysis probe detection format.   It is provided as a ready-to-use, stabilized 2X formulation that includes all components for qPCR (except template, primers and probe). This master mix does not contain a reference dye; however, a separate tube of carboxy-X-rhodamine (CXR) reference dye is included with this system, allowing users to add…
